WHEELED GUN-CARRIAGE.

Specification of Letters Patent.

Patented May 11, 1915.

Application filed April 26, 1913. Serial No. 763,846.

To all whom it may concern Be it known that we, WALTER HEILE- MANN and HEINRICH KANONENBERG, residing at Essen-on-the-Ruhr, Germany, both subjects of the Emperor of Germany, have invented a certain new and useful Improvement in Wheeled Gun-Carriages, of which the following is a specification.

This invention relates to wheeled gun carriages particularly intended as defence against swiftly traveling targets, such for instance as air ships. For the purpose of permitting an easy and rapid turning of gun carriages of this kind, they are provided with for instance a pivot stand. Such 'a pivot stand 0 consists of two parts, journal and bearing, connected by a vertical pivot, of which the lower part c is sunk down into the ground, and the upper part 0 connected with for instance the axle tree a of the trail A, see Fig. 3. The height of the pivot stand is therefore selected so that the wheels will be raised from the ground when the gun carriage has been brought to rest on the stand, whereby the gun carriage together with the upper part of the pivot stand may, without great exertion, be swung around relative to the lower part of the stand which has been inserted into the ground.

The present invention relates to a device fora gun carriage of this description which will prevent the digging into the groimd of the trail spade, and thereby facilitating the swinging around of the carriage resting on the pivot stand.

The object of this invention is attained by providing the spade with a shoe which may slide on the ground.

One embodiment of this invention is described in the accompanying drawing wherein: V

Figure 1 shows a side View partly in section of a trail end with spade and shoe;

.Fig. 2 a corresponding top plan view partly in section; and Fig. 3 a side view of gun and carriage together with the pivot stand,-

partly in section and in smaller scale.

The trail end A is provided with a spade B B adjacent its rear end, which'is composed of a spade shaped plate B and a pressure plate B In order to prevent the digging into the ground of the spade of the gun carriage connected with the pivot stand, a shoe C is provided, which is constructed as a tray shaped box, open on its upper side.

- lever G into the dot and dash line In the bottom of this box is secured a bearing D forthe spade plate B. This bearing is provided with a groove d for the deepest part of the knif'e of the spade and two perpendicular Walls d against which the spade may rest with its side edges. Two eyes 03 are arranged on the bearing D, between which eyes an arm E is mounted to turn by means of a spindle d. This arm E carries a hook e at its free end which is adapted to grip a shaft F mounted in a-bearing on the trail end A. The shaft F is provided at each end with eccentric trunnions f mounted inears a A flexible lever G is securely fastened on one of the trunnions 7, which lever may be engaged by a dog a situated on one of the trail sides A.

When using the spade shoe the trail end is seated therein with its spade plate B in such a manner that the knife edge engages with the groove (1 of the bearing D, and the side edges of the spade rest against the walls d of the bearing D. The arm E is thereupon laid, with its hook e on the shaft F, while the lever G has the position shown by dot and dash lines in Fig. 1; and the spade shoe under cooperation of the shaft F and arm E is then secured on the spade by swinging the lever G into the position shown in full lines. On swinging the gun carriage around the pivot stand 0, the spade shoe then slides with its bearing surface on the ground.

When it is desired to use the gun carriage as an ordinary traveling carriage, that is without the pivot stand, the spade shoe is detached from the carriage by turning the position. We claim:

1. In a wheeled gun carriage having a spade on the trail end, a tray shaped shoe, means for attaching the shoe beneath the spade, thereby providing a smooth sliding surface for the trail on the ground and a pivoted device for anchoring the gun carriage to the ground, saiddevice allowing an easy training of the gun carriage.

2. In a wheeled gun carriage having a spade on the trail end, a tray shaped shoe, means for attaching the shoe beneath the spade, thereby providing a smooth sliding surface for the trail on the ground; said means comprising a bearing piece having a transverse groove and vertical end walls for securely gripping said shoe and a pivoted device for anchoring the gun carriage to the ground, said device allowing an easy trainirg of the gun carriage.

3. In a wheeled gun carriage having a spade on the trail end, a tray shaped shoe, and means for attaching the shoe beneath the spade, thereby providing a smooth slid-..

' ing surface for the trail on the ground; said means comprising a bearing piece having a transverse groove and vertical end walls for securely gripping said shoe; a pair of eyelets on said bearing piece, a spindle secured'in said eyelets, an arm mounted to revolve on said spindle provided with a hook at its free end, a transverse shaft and eccentric bearings therefor on the trail, and locking members for securing said shaft in a certain position when said hook is in engagement with said shaft.

4. In a wheeled gun carriage having a spade on the trail end, a tray shaped shoe, and means for attaching the shoe beneath the spade, thereby providing a smooth sliding surface for the trail on-the ground; said means comprising a bearing piece having a transverse groove and vertical end walls for securely gripping said shoe; a pair of eyelets on said bearing piece, a spindle secured in said eyelets, an arm mounted to revolve on said spindle provided with a hook at its free end, a transverse shaft and ec-'
